The Shelly Multicolor Bulb E27 Gen3 is a color (RGB), dimmable LED bulb from the manufacturer, featuring adjustable white color temperature (2700K–6500K), along with Wi-Fi and Bluetooth connectivity. It can be screwed into a standard E27 socket, making it easy to replace any existing bulb while instantly adding smart functionality to your lighting. It is ideal for home use, offices, or small commercial environments where flexible control of brightness, color, and color temperature is required, either via an app or automation.
One of the bulb’s key advantages is that it operates without a hub, connecting directly via Wi-Fi, but it can also be controlled through Bluetooth using a Shelly BLU wireless switch or remote control. As part of the Shelly ecosystem, it offers advanced automation features, including scheduling, scenes, and even custom script-based operation. Thanks to its built-in web interface, it can also be fully configured locally.
The Gen3 version adds further benefits, as it can function as a Wi-Fi range extender and a BLE gateway, and supports the Matter standard. This makes it not just a lighting device, but an active part of the smart home network. With power monitoring, event logging, and advanced APIs, the product integrates especially well into advanced or even DIY-based systems.
